Racism = Nationalism when in White countries?

Europeans asked for it. Asians, Africans, Middle Easterners and Latin Americans did not asked to get colonized. So when they finally got there independence in the 20th century they wanted to build their own countries for themselves, while European countries were independent for hundreds of years (I'm talking about how the people did not get colonized, since some European countries didn't even exist in the time of the colonies).
